I am not understanding

but

You could hold the fitting as to where it is going to be and make the pipe and cut it to length

When soldering an assembly,it's best to solder a whole bunch at one time.The heat from the last fitting will transfer to the next and save you time. Just touch the solder to the older (still hot joints) to make sure that they are full.

The solder will flow into a very small space.Fittings can be placed 'back to back' and the solder will still fill the joint,

Soldering one fitting at a time usually leads to time wasted cleaning scorched flux and filing down solder drips.

Also if you are not using MAP gas--Go get some!!--MIKE--

yes-solder them both at the same time. Do not wipe your joints after soldering until they are cool.

If the joints are not soldered at the same time the heating of the second joint may soften the original one--If so then just brush on a little fresh flux and touch it with a bit more solder.-MIKE-

If you are soldering 3/4" fittings, definitely use a MAP gas, or spring for an acetylene tank (often found on craigslist for under $100).
