I totally understand where you’re coming from on this, @NOVUS. Depending on how far a zone is from your controller, three minutes may not be sufficient to even test/troubleshoot a zone - which is a prime use for this manual feature.
I’ll point out, though, that Limited Schedules are also a useful option for when your unit is offline. Instructions on using those should have come with your Gen2, but are also available in the following support article: What are Limited Schedules?
Hope that helps, until the changes Ben mentioned (in Post#2) are put into production.
