Android Question Memorizing the state of #Regions and Subs

I think the possibility of creating #Region and being able to expand and collapse the content of both Subs and Regions is fantastic, however, in very large code, as is my case, I find it useful that some SUBs or REGIONs remain collapsed because they have to be manipulated a little and others expanded by needing constant manipulation. I organize my code by opening or closing items, however, when saving the project and reopening, everything is as before. Items do not remain as I left them. Is there an option I'm not aware of that activates this? If not, how about that possibility? It helps a lot to deal with large code!

Thank you very much!
