Thanks for the concern Jan. There are a few reasons why filtering won't work, but the main one is, the Task List is sorted and formatted with blank rows to keep tasks separate. It also group tasks together with their subtasks, and if we filtered, it would get rid of the formatting and just merge everything together.

I realize it's a stylized things, but this spreadsheet is design for "user friendliness", so it's not just straight data dump.

Again, I appreciate the tip and thought! We will monitor the named ranges and if it bogs down the system, we'll readdress it.
