Insert Row (Based On Values In Range) With Sum Of Values For Other Columns

I have different reports, some have fifty transactions, others have thousands. My goal is to: Insert a new row every time the values in the "Account" column meet a certain criteria, AND THEN add the totals for the Debit and Credit Columns.

Let's say I start with a table that looks like this:

A
B
C
D
Dept
E
Account
T
F
F2
G
Debit
Credit
Total

33010

[Code] ....

I want to group the first four rows because Accounts 33010 and 33015 are in the same department. Same with 50050 and 500060. I want to then insert a row below the last row with "33015" as its Account #. And add the values for Debit and Credit. It'd look like this:

A
B
C
D
Dept
E
Account

[Code] .........

Honestly, I have tried everything. Running a Macros with Relative reference does not cut it.
