Reactive Transport Modeling: Multiple injection stages

Is multiple injection stages possible in OGS? I plan on creating a Reactive Transport Model for microbially induced calcite precipitation with the following sequence: (1) bacteria injection for 60 mins with specification for attachment rate of bacteria to soil, and (2) chemical injection for 60 mins with specification of rate for kinetic reactions such as biochemical reactions, and calcite precipitation. The solutes will be injected in at the middle of the subsurface to allow a spherical distribution (permeability_x = permeability_y)

Dear Oliver,
It is possible to use different injection strategies, check this benchmark:
