Yes and no. They call the block a "square on point". Here's the link to the sizes available.

The problem is that you still need the corresponding HST die to complete the patch. They don't tell you which size HST die you need, or what the finished size of the SIS patch is. The only place I could find the info is to go the page for that specific die, then watch the video. For instance, the GO! #55106 Square on Point-3 11/16" (3 3/16" Finished)
needs the 2.25 HST, yielding a 4.5" patch
