Hello AnneMariee,
The steps you have provided function the same way as a transfer when I gave it a try. It just adds an extra step.
-I created an equity account that has no balance in it
-General Journal Entry: I debit the amount owed from business checking and then credit the equity account. (no where could I categorize this)
-Equity account now has amount to be reimbursed 
-General Journal Entry: I debit the amount owed from equity account and then credit personal checking account
(so far has not changed anything on the P&L)
-Unsure about writing a check, it just debits the personal checking account a second time. (the first time being when the credit card was paid)
I tried writing a check straight from the equity account but I'm not allowed since that isn't an actual physical account. 
Perhaps I am misunderstanding the sequence or I've missed a place where I'm allowed to categorize it at any step of the process. Thanks
