Someone make me an "Import XDR" function for Laboratory's transaction builder? Please!?

Picture this:

You've spent time carefully crafting a series of transactions, each containing multiple payment operations, a specific memo, and the correct sequence number. The transactions will need to be submitted in the correct order, of course. Everything looks great! Only, after a while you realize that the First transaction has a missing or incorrect memo. They're all still un-submitted, but that first one now halts any others from being submitted, because that would botch the sequence numbers, and mass chaos would ensue.

Wouldn't it be great if the transaction builder on Lab had some kind of "Import XDR" functionality so you didn't have to re-create the entire transaction from scratch, just to add one little memo!?

Could make a pretty sweet bounty, if somebody wanted to write that up 😉
