Who knows. They might not have the shells to do it, might not be set up to do indirect fire, might not have accurate enough data on their location to guarantee effective fire on an important target. If you have to put someone out there to get you a proper target anyway then it might make more sense to have them try and take it out than to have a second team emerge somewhere else as an improvised artillery section, then try to aim at a designated target while not getting their shit rocked out in the open wherever they are. At least if you're mixed in with your enemy in an urban environment you deny them the ability to just level your grid square.
Unless they had a couple dozen Zakus and appropriate cannons, they wouldn't be able to do enough damage fast enough before getting levelled by counter-battery or air power if all they know is 'in that city'. Given that they allowed a single Gouf to go on a suicide mission to get the job done, I suspect they didn't have those resources spare.
At some point you also just have to decide if you want to watch a cool robot fight or not. I think it's pretty reasonable here with how much Zeon's been rolled back into their bunker and worn down that they can't manage anything more.
