Combine Multiple Like Sheets Into One

I have a worksheet that has about a dozen sheets that are all the same, just different data. Each sheet is like a checkbook register that has date, memo, amount.... each sheet is for a different account. I have a form that I enter the info into, it puts it into the right sheet and sorts that sheet. This part all works.

But now, I want to take all the info from the different sheets and combine it into one master register sorted by date. I won't make changes to info in this master register, it would just be for info, so it doesn't have to work backwards. I need this to be automated.

Obviously, it's easy to copy all of them to different areas in one sheet, but I want to have them all in the same columns, and that is what I can't figure out. My sub registers don't have the account name listed for each entry, as it isn't necessary as the registers are labeled. But, the entries in the master register would have to have them to figure out where they came from. I can solve this by adding it to the sub accounts and hiding it or something if that is the easiest way. I also need to make sure it doesn't remove duplicates.
