Bait station: bait by blocks instead of gramms

Most of the our RatBusters have not been using the app so far, but report (via excell sheet) on the number of bait blocks placed and retrieved. Now it appears that you can only set up bait station in the app with bait added/retrieved in gramms.
It would be great if you could set up the app to have that count in blocks, meaning entering the weigh of a block somewhere which then would automatically calculate the total weight. Should be easy enough to program and would avoid to have our sometime elderly volunteers needing to calculate say 7 x 28g = ???
(not speaking about our younger ones who would need a calculator…). Even by making it easier to round up to say 7 x 30g would pose a challenge to some and result in inexact figures
