It's not a silly question, it makes perfect sense
But no it is not possible right now. But it would be a good option to have. I actually thought about this a while ago, actually, what I was thinking was to also automatically-shorten URL's with tinyurl or a similar service. We could have a new option and call it "Auto Link" with three options - 'None', 'Standard' or 'Yes and Shortened'.
This would should be very easy to do, and we should be able to add it to the next release. I've added it to the tracker
here
.
Thanks for the reminder there, but most of all thanks for the feedback
