Bulk edit YT descriptions?

[Tito Tims Videos]

I know I have done bulk editing of my descriptions before - using a find/replace feature. I do not remember if it was in classic or beta. I need to change the web address of my blog - in all my video descriptions (but only that one line). I looked in the bulk tools on both classic and beta and the find/replace does not seem to be there? Anyone know if this is still available? And where? Here are all I see for bulk editing on descriptions

Classic



Beta

I'm only familiar with it being a function of TubeBuddy.

I know TB does it, but the free version only does 1 vid at a time (may as do it myself ha ha). I added my PO Box to all my descriptions a few months ago, and thought I did it in beta. But it is not there now. Bummer.
