How to choose more then one file in RStudio Server GUI session.

Hi. I asked this question on Stackoverflow but they said it is not a programming one.
I am trying to run my script on Ubuntu server with installed RStudio Server but without window manager. When I try file.choose() it works perfectly fine. But I need to let user to choose a bunch of files at ones. But all ways to do it I know, like tcltk, demand X11 installed. Can I implement multiple file choice in my script using just Rstudio Server GUI with no window manager installed?rstud
upd: uploaded a picture showing that file.choose() works fine.

Thanks

Unfortunately, multiple-selection is not yet implemented for the RStudio file dialog. Would you mind filing this as a feature request at https://github.com/rstudio/rstudio/issues?

Absolutely, thank you.
