Arithmetic Operations?

Hi,

I was wondering if the Web Sources Framework supports Arithmetic operations?

I'm working with several limited web services that don't offer the amount of tracks an album has as a value. I need to calculate this by looping over the track items and get the last track number.

The issue with this is that the last track number does not have to match with the total amount of tracks because:

  • List order is not correct
  • Album is a multi-disc release and tracknumber is number on disc

If this is not currently possible is this a feature that is on the roadmap?
