RAC-aware TOAD AWR/Statspack Browser Custom Charts?

recently I find myself in environments where TOAD's AWR and Statspack Browsers are used.

If you stick to the pre-installed Charts, then those are plotted for the selected instance only. Now, I want to have the same for my custom reports. There seems to be no documentation of the custom chart feature aside from the short hints in the dialogs. And these only mention "&Snapshotlist" as a placeholder for the snapshots. What I need is a placeholder like "&Instance_number" - using TOAD's SQL Tracker, I saw that TOAD itself limits the results to the chosen instance_number, so there should be an according placeholder defined somewhere.

Does anyone here know about such a variable/placeholder (I fiddled around a bit with guesswork, but to no avail)?

Cheers,
Uwe
