No, and deliberately. A star is something you can write and read back a month later; a regular expression is something people paste from an answer online, and a wrong one quietly redirects part of a site nobody was looking at. A star covers the case that actually comes up, which is moving a section.
That is also why a regular expression kept by another redirect plugin does not come across when you import from it: it is listed as staying behind, and keeps working in that plugin for as long as you leave it on.
Still stuck? Ask the developers who wrote it. We aim to reply within one business day.
