Hi @Smiroc,

There's no API method that will return this for you. The way I see it, is that you have two options:

1. You can query all 50 items, grab the runtime of each and do the math yourself.
2. You can add all of these items to a list, which happens to have a total list runtime value.

If you do options #2, it should be noted that for TV series, we only use the TV series values and not a calculation that sums up all of the episode values. So that might not work very well for you.
