KMyMoney

I'm paying my Credit Card Bill, via Check from my checking account. both
accounts are in kmymoney2.
I don't want to set a Category as the categories are already in place via
transactions. I'd rather monitor the interest instead of how much my credit
card bill is.

1 interesting thing I did notice is that when I went to go enter in this
transaction in my checking account. I clicked on the Check tab. As soon as
I put in that I wanted to transfer the money to my credit card account it
disabled all tabs except transfer, yet didn't switch the tab. So I finished
entering in all the data including the check number. Thankfully even if I
edit the transaction it never gets rid of the check number even tho
transfers don't have a field for it.

Am I just going about this really weird? Is there a better way (aka, this
is the desired function.) Or has no one thought to do this?(or at least
report that they want to do this?)
