At my store, they've told me that as the current signing TM, I will still be responsible for breaking down and sorting the signing pallet and doing all "Operational" signing, such as overheads and big builds. I'll be given the time to do that in the schedule.
As far as the other signing goes, that falls on the individual areas. For example, the Hardlines TM in HBA will be expected to handle getting the headers when they set a salesplan, signing the electric toothbrush displays, etc. This is in addition to setting any POGs and revisions for their areas. (All on 5 hours or less)
What isn't clear is what I'll be doing with the rest of my time. I may be assigned a hardlines area, I may bounce around as a backup in other areas, the backroom, helping with bigger POGs etc. Same goes for the current POG team. They said they'd probably bring us all back together for the big seasonal resets and things like the recent beauty set, etc. (That's if we all stay and can sustain ourselves on working 6 days a week and still not getting 40 hours).
Originally, we were told that we'd carry on more or less as normal but they'd hide us in the schedule. But apparently corporate is looking out for that or something, because now they're wanting to do it by the book.
