1.2.0 - Using Manage Columns - saving

[info4km]

I am checking out 1.2.0 and I was looking into the "manage columns" feature. If I am in specific project (e.g. myproj1) how do I save my column changes to that specific project? the drop down menu never contains the project I am currently in. For example in this case if I wanted to save the columns (that i just re-adjusted) to myproj1, only myproj2, myproj3 etc appears in the dropdown, and not myproj1.

Am i missing something in the way this works? I couldn't find info in the guide. I probably would set up the same columns for all projects, but in case i wanted to save my configuration for only one how can I do it?

Thx
