Steemconnect URL for conversion now works too so it's a snap if you already trust them. Sample URL for anyone following along:
https://v2.steemconnect.com/sign/convert?requestid=1&owner=eonwarped&amount=5.000%20SBD
Change user, change requestid to something like 20181601 or something.
Another great option. Giving this one a test out now too. Thanks for the tip! :)
