For gas storage you'd have a "pump" or "pipe" construction that you'd place like an extender with two ends and you'd bury it by building a wall on it with the ends sticking out both sides, one you'd connect to a machine or something and the other would check if it's side was a sealed volume whenever you try to turn it on and if so it'd act as gas storage equal to the area's volume, naturally if by digging it's ever connected to a volume that's too large or not sealed it would all be lost, if it's connected to a volume filled with some other gas(like air) it would instantly mix and be unusable until filtered which could be an attachment to the pipe. there would be other possibilities like having an airlock that'd be like a pipe but would allow passage without gas flow so you can build atmosphere specific things, for example titanium refineries would only work without a purely unreactive atmosphere like IRL or planters would only grow with their home atmosphere and a source of lighting(or transparent terrain to let the sun in). Beyond that you could have simple liquids that would just fill up an indentation up to a flat level depending on volume, once the level reaches an edge it would send out a "stream" that'd follow the steepest slope from whatever point it's at until it either reaches another liquid surface or a point where there's only up slopes at which point it would make a new one into which the overflow from the originating reservoir would flow into the new one, if the new one fills to the point that their levels are both the same then they mix and continue upwards as one, if they drain past that that point then they split again. you could also do something with multiple levels of different density fluids and if you have a reservoir inside a gas room then the gas room would have a reduced volume depending on how much the liquid takes up. In short I feel the dynamically modifiable terrain should be more important to construction.
