Mass-apply tags to programs?

Hi folks,

we have been sloppy in applying tags to programs. Now that we clean stuff up and also have new reporting requirements we need to add tags to existing programs. Is there any way to "mass-apply" tags to programs? Like in adding tags to a group of programs or a folder where certain programs live in?

I suppose not, but I wanted to double check before I start rolling the boulder uphill.

Thanks,
Michael
