LCR Switch between callings

I have been called to assist with finances in 2 different units in our Stake. I'm an out of unit member of a branch and have a finance clerk calling which shows up in LCR. I also have a calling in my home ward but I do not know how to get access to LCR for my home ward as per my assistant finance clerk calling. Is there a way to toggle LCR between those 2 callings?

Generally when you have two callings there is a drop down box that lets you select which one to use. This is true for callings within the same unit at least. I would assume it's also true for callings in different units. The drop down should show up in the upper right side of the screen by the unit name. It's possible that the unit name may also be a drop down to select which unit. That's the case for stake callings which have access to all the units in the stake.
