It seems to be possible to input FX Rates at Quarters and Years, does the system actually use this 'year' and 'quarter' rate across the periods for translation?

FX Rates Input at Year
This may be a silly question, trying to consider budget and forecast rates and how they will need to be input in OS.
I understand OS does not have the same concept that HFM did with holding rates in balance recurring account.
However it seems to be possible to input FX Rates at Quarters and Years, does the system actually use this 'year' and 'quarter' rate across the periods for translation?
I thought this was rather clever if this actually works as typically you would have the same Budget rate across 1 or 2 years, so don't need to populate 24 periods with the same rate data effectively...
