Conditional Formatting against another Field - Request for Enhancement

Hello!

We would like to be able to apply a conditional formatting for the following:

End Date goes past Must Be Done By date

Reason:
We have production schedule the frame work for all tasks leading to a client posting. The departments then can individually schedule their artists Start and End dates.

But when things shift, going past a Must Be Done By this is a manual process of notification. With the volume we have to process - it would be amazing to have a Conditional Formatting.

The current base code only formats based off one field… but could we get it to cross reference and flag End (field) >MBDB (field)?

Cheers,
josa
