How can I create a patch that spans commits using Sourcetree?

unknown

I observe that when I "Create a patch", the dialog creates the patch that is "to" the commit I selected "from" it's predecessor.

In the dialog, I can tantalisingly select two separate commits and the diff panel shows the diffs that are between those two - that's the patch that I want.

But when I press "OK", I still get the single commit patch.

Is there some way to achieve what I meant.

When you select 2 lines, it actually shows you the diff *between* these two lines. To be consistent with this, that's the patch that's created, so if these commits are next to each other the difference is actually only the later commit (since the first is the base). Select a wider range to generate a patch for the difference of both commits.

I realise that may not be intuitive, there's a clash here between 'difference between two commits' and 'changes in selected commits'. Since the diff / log always works on the former this sheet also works on that basis.
