Matt87:
I had C and C+E provisionally added to my license before I had my C, you can tick both boxes and they’ll add it on for you.Good luck in your training buddy, I am glad I did it.
No you didn’t and no you can’t.
Gov.uk:
You can only apply for a provisional trailer (+E) licence when you’ve got the full licence for the vehicle you’ll be driving

The OP also doesn’t have provisional artic either, he will find when he checks his counterpart online. You can only have a car licence and you will still have all of those empty boxes with a line through in each category
