Update custom.less file without overriding original file

Question

Hi there ! 
 I have a question regarding the custom.less file. I already did some modifications on our customer's instance within the custom.less file. 
 I will upload a plugin that we did with some custom style within the custom.less file. When I uplaod my package the original custom.less is overriden. How can I manage to avoid this problem? Is there a way to create another XXX.less file that will be loaded ? 
 Thanks in advance for your feedback. 
 Best regards, 
 Enes

Hi Folks, 
 Yes it would be a nice enhancement request. Could you please add that idea to our portal? 
 But for now, you'd have to maintain or make some sort of maneuver through pre-install to have your code appended to the current custom.less file.
