Load multiple samples or a cohort through the UI

[skchronicles]

Hello @sehilyi,

I hope you are having a great day! Before I get started, I just wanted to say thank you for creating this awesome tool. Chromoscope is amazing.

Would it be possible to add a mechanism that allows a user to load multiple samples from config through the UI? I was thinking it would be awesome if a user could point to a multi-sample config file as described here via https or as a local config file, it would be awesome.

Some thing like this would be perfect:

Please let me know what you think, and have a great day!

Best regards, @skchronicles
