SUMMARY
If in the ledger form view you wish to create a new sub-category for a new item you are entering, KMyMoney appears to allow you to do this in the same way as you would select an existing sub-category by using the:
Category:Sub-category
syntax. However, the resulting "Create a new Category - KMyMoney" form that opens does not have it data fields correctly populated to achieve this. It appears that the ":" character is not recognised as the delimiter between the category and sub-category names. I believe that the ":" character is not allowed in a category name?

I will attach a PDF with screenshots for a new sub-category creation using the "Categories" tab, that works as expected, and one from the "Ledgers" tab that does not work as expected. 

STEPS TO REPRODUCE
1. Create a new expense entry in an account in the "Ledger" view
2. Create a new sub-category by entering for example "Insurance:Cycle Insurance"

OBSERVED RESULT
The "Create a new Category - KMyMoney" form that opens does not have its "General Tab"-"Name field" filled in correctly and the "Hierarchy Tab"-"Selection" is incorrect.

EXPECTED RESULT
The "General Tab"-"Name field data and "Hierarchy Tab"-"Selection" should be set as expected to created the required new sub-category.
