Custom format a number list that contains a hyphen

In my data the account field contains two sets of data formats. An 6 digit and 10 digit.

Example:

Account #
4444-22
4444-20
22-666666-22
22-666666-20

I would like to format the list to the 10 digit format using 00-000000-00 as the format.

How do I format the 6 digit numbers that contain a hyphen into a 10 digit format 00-000000-00 with leading zeros.
