You'll need to either symlink or sync the CCCT savegame folder across your servers. Sync can be done with e. g. dropbox or similar software/cloud storage solutions. This system does write uploaded items and creatures to savegame files with steamIDs as their names. You'll find it at this location:
../Steam/steamapps/common/ARK/ShooterGame/Saved/Config/SavedArks/CCCT

this game.ini is usually located at
Windows:
..\Steam\steamapps\common\ARK\ShooterGame\Saved\Config\WindowsNoEditor\
Linux:
../Steam/steamapps/common/ARK/ShooterGame/Saved/Config/LinuxNoEditor/

Main tag to put above, only required once (in game.ini)


Limit the amount of maximum uploadable items that can be stored in the savegame. You can also set this option to -1 to disable upload limitations. But be aware that the implemented ingame widgets do not use paginations and therefore can crash clients/servers if you have for example more then 200 items uploaded (due to replication timeout).

Limit the amount of maximum uploadable creatures/dinos that can be stored in the savegame. You can set this option to -1 to disable upload limitations. Similar to MaxItemUpload, be aware that more then 200 uploaded creatures could be problematic.

Default are 86400 seconds = 24 hours. Means after this time, like with Wildcards terminal upload, that items will expire and get pruned. This can be deactivated if set to -1.

Similar to MaxItemExpirationTime.

Blacklist certain item classes with class pathes. Needs to be a comma separated list. Example could be:

Does only blacklist blueprints of this class from being uploadable. Example could be:

Requires class pathes to force uploadability for certain item classes. This does also override the vanilla prevent upload setting of items like Element.

Similar to ItemClassBlacklist. Can blacklist ceratin creatures/dinos with a comma separated class path list.

Enforce uploadability of certain creatures/dinos even if they are listed in the blacklist or are otherwise blocked for upload.

Set this option to true if you want to block all flyer creatures/dinos from beeing downloaded onto this server. Means you'll still be able to upload but you can't download them again.

Wether it should be possible to permanently be able to pick the terminal up or not.

Determines if download sickness should get removed and Titan beeing ridable again or not. Default is like vanilla.

This option can be used to determine a custom savegame path. Trailing slash (/) is required.
