Can we have the ability to set prices for entire merchant tabs?

Just now in the process of dumping my stuff from last league into a non-remove only tab to sell. I'm selling all my jewels for 1c, and maybe later I'll change them to 1ex, because I don't know if I really care about having currency in standard, maybe my jewels can find a good home with a standard enjoyer somewhere.

So you know, it'd be nice if I could just price an entire tab instead of doing it individually. I appreciate that this might lead to mistakes, but it would be my mistake. (Also, if streamers make this mistake I will appreciate the opportunity to laugh at them as if I've never done it myself when I will have totally have done it myself once or twice, lol.)

I need that too. And ability to delete all items inside tab after confirmation.
