Describe your enhancement

Self explanatory, one of the bugs (that I'm gonna open issue on) made a huge mess out of hundreds of patterns and I would like to do them over again rather than trying to find proper patterns in my inventory, most of them are also obsolete so I'd like to have a way to clear them so they could be overwritten through pattern grid.

I know that I can slot them in but that sadly not an option because written patterns don't stack.

Shift rightclick with pattern in hand

I have hundreds of them in the grid. It's not really practical, sadly.

Don't really like the idea, since you won't end up with that much obsolete patterns in a normal playthrough.
