Setting up Auto reversal with more alternatives for a journal category?

We have journals with a need for auto reversal for all months during the year except for December.

This is related to files sent YTD during the year. All journals before December needs to be reversed as the new file for the next period are YTD. In December we have the correct YTD file and we don’t want it to be reversed.

How can we set that up to be automatic during the year, including December period?

We also have journals that needs to be reversed in the middle of the month. How can we set a specific date within the next month when the reversal should run?
