OK,
I just tried several ways that I could think of to accomplish this. Give this a try to see if it fits your needs.
Is the folder located on a Citrix server or on another server?
If it is on another server, publish it as Content as \\Servername\Share$. Users will not connect to Citrix, but be prompted to login to the share during access.
I tried some other ways, but wasn't very successful. I'm sure there are other ways, but I think the above should be a sound solution as it shouldn't use a MF Connection License. (???)
