Multiple tablature tracks?

Hello,

I've been using SP for a couple of weeks now and I'm generally very pleased with it. However, one thing I've noticed is that it seems impossible to have multiple tablature tracks. While I can add multiple guitar tracks using standard sheet music, I've found no options for tablature, memorizing the tablaturefor the second guitar part is a bit of annoyance

Am I just missing something, or is this not a feature yet?

Thank you for reading.
