[Inkscape-user] Can I do this in inkscape?

I have personal die cutting machines, that I use for scrapbooking, In another software, when I make a mat for a title, I can have it three ways, one is rounded, then next is squared, and the third is mitered. When I make a mat in Inkscape, I do my title, welding them if I want, then I duplicate that word, and use outset to make a mat, thus creating a rounded mat. Is there a way in inkscape to do squared or mitered cornered mats?

Thanks Bibi
