Yes, but rather manual setup.
After inserting the USB drive, right-click on (My-)Computer and select 'Manage'
Under 'Computer Management' -> 'Storage' select 'Disk Management'
Locate the currently installed USB drive and in the lower panel, right-click this drive (partition) and select 'Change Drive Letters and Paths...'
The current Drive Letter should be shown. Select 'Change' and in the drop-down select the drive letter you want to assign.
Wash, Rinse, Repeat.
If Windows is behaving normally, the next time that USB drive is inserted, the last drive letter definition should return. Windows is a bit schizophrenic at times, so you will need to keep an eye on the drive letters and adjust them if they change.
