Hi Dennis, indeed pointing model software is generally suited to permanent installations... however having stated this, the software can also be easily utilised to accelerate precise polar alignment for non-permanent installations. In most cases eliminate the need for drift alignment.
Simply load an existing pointing model based on equipment/location set up (note: you must have already created this). Sync a few stars and the software will let you know how far off polar alignment you are. Once you've made changes in AltAz/Dec, repeat the proceedure (sync a few stars) to confirm the precise polar alignment.
You may wish to check out some of the information on such modeling operations:

The link has some specific Paramount ME content, but conceptionally the details apply to other mounts.
I'd like to note, that some mounts such as ones controlled with Gemini controllers have built-in pointing model capabilities. Every time you perform an additional align on a star the point model accuracy improves. Though, it does not replace the advanced multipoint models that TPoint and Maxpoint can achieve. Also to use TPoint, ideally you should also be using TheSky as the two product intergrate tightly.
