Many times i've created my drum/rhythm/bass line in say 16 rows, but i want to create a 32-row pattern with the same line. I can double the rows with the Pattern Properties dialog row pretty easily, then select the rows in question, and paste the rows at the 17th row. But there's got to be a better way.

Would love a shortcut (or perhaps an option in the Pattern Properties) to duplicate the number of rows in the pattern, and append a duplicate of the existing rows to the added number of rows.
So, for example, if i have 4-on-the-floor drum beat in a pattern of 16 rows, "Double Pattern" would create a 32-row pattern, filling the added 16 rows with my 4-on-the-floor beat, saving a lot of clicking, dragging, copying, and pasting.

For even better flexibility, we could have a "Tile Pattern" option, where you could add an absolute number of rows, filling the new rows with whatever notes are in the original rows, until all the rows in the new pattern are filled with the existing data. I don't think this could be in the contextual menu, but it can definitely be a part of the Pattern Properties dialog. ;)
