I have uplloaded few liveries for 2 mod cars , the issue is if we submit more then one livery it will not assume automatically after subscription because making filename=liveryname1.png,liveryname2.png seems not recognize the separated files , this not made sense because if someone decide to made 300 liveries for same car it has to do 300 submissions what it will spam the workshop , my question is there's other way to have several liveries for same car in one submission and make it work automatically only by subscription ?

This question is for devs because there's a lack of info about making this work properly .

Thanks
