The matter of choice will be made available. More to come. PWSweather / Aeries Weather are working hard at improving their services.
It is now 2021-01-03.

Yes, there is now an option in your PWSWeather Station edit screen to set pressure to MSLP, Station/Surface Pressure, or Altimeter. I have selected MSLP. There's a disclaimer there that it's still a beta option and they're working on correctly displaying the data based on your selection. I'm see that option has been available since November.

1 months later...

My GW1000 says 30.133, WU says  30.13, and PWSWeather says 29.96

Note that KFHU, my local METAR, says 30.14 on PWSWeather. I'm guessing because it is a METAR, the data is pulled from elsewhere, so they get displayed properly.

...just one of the reasons I still use WU. They, at least, display the proper pressure reading.

UPDATE: May 8, 2021

If you click on the gear icon on the dashboard yes, you can now choose  MSLP, Altimeter or Station [Pressure] but...if you click on MSLP you get Station Pressure (ABS). If you click on Altimeter you get REL. If you click on Station you get ??.

Here are my current readings from the Ambient WS-2000 display console:

ABS = 993.8
REL= 1016.6

Here is what the PWS Weather dashboard shows:

MLSP=993.7 (rounding?)
Altimeter= 1016.6
Station=1017.2
Interestingly ,WeeWX shows Barometer(MSLP) = 1017.2
