Hi all, I am struggling to filter for options that expire quarterly when using the AddOption method in Python.

I was wondering if, as in the page linked above, there is a quick way to call only options that have a quarterly expiration in the options.SetFilter (as you do with weeklys) or if any of you can suggest an efficient way to code this, thank you.
