No way to add a fourth class to PF1e character sheet?

I tried manually adding things like class4_name etc. but that didn't seem to work. I take it this isn't possible?

Hi Andy,  On the character sheet itself I don't think there is a way to do a 4th class. However, you may be able to do workarounds.  If you would like advice on that please let me know the class, etc. 

I'm trying to add a single level (for now) for Warpriest. The other class levels are Swashbuckler 1, Monk 2 and Bloodrager 7. Yes I know how goofy this build is.

Alright, here is my suggestion:  We are going to combine Bloodrager and Swashbuckler into one line.  Name: Bloodrager(7), Swashbuckler(1) Level: 8 HD10 Fort: 3 Ref: 5 Will: 3 Ranks: 4 SC: checkmark CL: whatever is appropriate for Warpriest (but not Swashbuckler) etc.  Warpriest and Monk are set up normally.  If there are any tweaks to be made to powers and abilities they can be made in those abilities. Let me know if you run into any issues with those. 

I'll give this a try tomorrow when I have more energy, thank you!
