Here is how I did it.
1. Pick the player you want in a util position
2. When looking at your roster page, right click on the link and copy the address bar, it will look something like this
the 2194466 is the unique player id (1894 hugh duffy) and the "add&spot=9" is the position on the roster of the player (the first utility spot. C will be 1, 1b will be 2, 2b 3 and so on)
3. delete player from your roster
4. Paste the link, that you had already cut in step 2, into your toolbar
5. Where is says "add&spot=9" change 9 to what position on the roster you want him to occupy. (1=C, 2=1b, 3=2b, 4=3b, 5=ss. 6,7,8=of....)
6. Type enter
7. Player should now be there. Rinse and repeat.
