Consistency between RS+ rtk surveys each with different Base ave single pos

A query from a newbie working with GNSS data from Patagonia (thanks in advance!):

If we did several daily surveys using same base location but each time using Average Fix Position of 30min, I understand that all rover acquired points will be relative to a different Base position - how to make all the survey data consistent to a unique Base position?

My first thought is to use the base raw data longest log to get absolute Base pos (using CSRS since nearest IGS station 10 km away hasn´t got the data since 2020, and the next one is 385km away). Then use RTKPost with that Position for the Base for each survey day.

thanks in advance
