Make the Formula tool's input anchor optional

[DataNath]

Hello all, just another little QoL suggestion!

There have been a few occasions recently where I've been adding some Report Text to a Rendered output and have needed to reference the current date. However, when building a quick formula to do this, I've first needed to add a dummy field within a Text Input tool so that the Formula tool doesn't error due to no incoming connection.

I know I can create a branch off from the main dataset and just use that, but for something simple like this, I find it cleaner to isolate and generate it in this way and so it'd be great if - for situations like this - the Formula tool's input anchor was optional (obviously only when using it to create new fields).

There are likely many other examples where you may want to build a simple workflow (or branch of one), starting with a quick field generated within the Formula tool itself. However, just thought I'd raise this with a scenario I've encountered a couple of times recently.

Cheers!

This would be nice!
