Like Frank says, sorry no.
But consider that at least one of the 'other' Civ games allows a player to stop & start tech research without much penalty.
It works like this for example:
Start researching Alphabet some year...
Accumulate some years of advancement but not finish...
Change to research to Construction...
Finish this advancement (or not)...
Go back to researching Alphabet at almost where you left off (there is an incremental loss due to time away from researching deducted).
