Is there any way to add a custom column that the Funder could actually customize? For instance a "comment space". Sometimes we put an application back into draft and it would be nice for that application to stand out from other ones in draft by putting a red flag or brief note at the end of the columns.
One way I have seen this achieved is bad an internal question to your application form, this could a radio button or maybe an internal text area to type up your notes. You can then add the internal question into your custom columns.
As for your idea about flag we have talked about this at You Fly We Buy in the past but normally it is in the context of an organization not request. If we were to go down the “flagging” idea how many different flags do you think you would use?
