Do you mean SU-122s specifically or even JSU-122s?

The latter at least were used for such missions.

Time to time, JSU's used for artillery missions because they were able for both direct and indirect fire. In particular, during the Sandomir-Silesia offensive operation, the 368th Guards OTSAP of the 1st Ukrainian Front was assigned for artillery mission and for 107 minutes the regiment fired 980 shells.

As a result, two German mortar batteries were destroyed as well as other 8 German guns, about one German infantry battalion was wiped out. Interesting to note, that additional rounds were placed at the vehicles, but anyway, JSU's used their "internal" ammunition first. Otherwise, rate of fire become slower because it takes up to 40 minutes to load 20 rounds into the vehicle.
