How do I bulk redirect all links like below:
www.mysite.com/A1111
www.mysite.com/A1112
www.mysite.com/A1113
...

(for all the links, the last 5 letters start with "A", and followed by 4 digits)

to
www.mysite.com/go/A1111
www.mysite.com/go/A1112
www.mysite.com/go/A1113
...

I have several thousand such links.

Thank you.
