agreed, this would be very helpful for me too as I have many dozens of current / former meds and supplements on my list however I can understand why this might be difficult to accommodate given I’d imagine some users don’t use groups at all, and it might possibly be further complicated by meds that appear in multiple groups?

however if one already has such meds grouped in a way that suits individual needs, I think there’s a relatively simple change that could be implemented to provide a workaround for finding, and recording having taken, “prn” (intermittently used) meds - a “deselect all” toggle

for example: as well as having groups for my ‘standard’ am / pm meds, I’ve created other groups such as one of about 15 meds called “analgesics - prn”. and whilst I understand why clicking on a group gives a popup which defaults to all of its meds being selected (for routinely taken groups of meds this makes sense, and it’s extremely helpful), if there was also a toggle switch in the header section next to the settings icon that one could, if required, change to “deselect all” that would make it much easier to simply scroll through and select the typically one or two meds needed from that particular group, rather than having to go through the whole list manually deselecting the bulk of that group’s meds which aren’t applicable for that entry
