Managed to solve issue 1., though probably not as elegantly as I could have,
by using the following to generate a list of lists with the summary variable(s):
```
grenerator = [([x for x in table.schema.names if "c" in x][i], "mean") for i
in range(len([x for x in table.schema.names if "c" in x]))]
table.group_by("IDs").aggregate(grenerator)
```
The second part however, still eludes me.
Would I be better off filtering by ID and then running the `mode` call
individually and appending?
