I got a problem with the renaming of one PDF splitted.
I have a PDF, with two pages inside, named 1807NF10#, after that I had split it I would like to rename the 2 file in this way AEX18C10 and AEX18C11.
This is the flow I created:

And this is the rename job I created:

As you can see I created 5 actions, the last should have regular expresion that permit to change the last two characters in sequential mode but I'm not able to do this...
Someone can help me?
Thank you!
