Formula Looping

[Jborhi]

First off, I love this plugin. However, I've noticed with larger tables there tends to be many repeated formulas to accomplish basic tasks.
Take the following table as an example.

| test 1         | test 2 | test 3 | test 4 |
| ----------- | ------ | ------ | ------ |
| Banana      | 1        | 2        | 3        |
| Orange      | 2        |           | 2        |
| Cherry       | 2        |           | 2        |
| total          | 5        | 2        | 7        |
<!-- TBLFM: @2$4=sum(@2$2..@2$3) -->
<!-- TBLFM: @3$4=sum(@3$2..@3$3) -->
<!-- TBLFM: @4$4=sum(@4$2..@4$3) -->
<!-- TBLFM: @>$2=sum(@I..@-1) -->
<!-- TBLFM: @>$3=sum(@I..@-1) -->
<!-- TBLFM: @>$4=sum(@I..@-1) -->

It takes 2 formulas, repeated 3 times each to accomplish both horizontal and vertical total calculation and only gets worse as the table grows in size, forcing repeated formulas to be added and leading to potential error.
Ideally, there would be some function that could iterate so many times similar to a for loop.

The row sums can be merged by setting last column at once. This works because omitting the row from the destination applies the formula to all rows after the header.

| test 1 | test 2 | test 3 | test 4 |
| ------ | ------ | ------ | ------ |
| Banana | 1      | 2      | 3      |
| Orange | 2      |        | 2      |
| Cherry | 2.     |        | 2      |
| total  | 5      | 2      | 7      |
<!-- TBLFM: @>$2=sum(@2..@-1) -->
<!-- TBLFM: @>$3=sum(@2..@-1) -->
<!-- TBLFM: $>=sum($2..$3) -->

I don't think this is possible here for the column sums because the first column is non-integer. Trying to use <!-- TBLFM: @>=sum(@2..@-1) --> parses (silently) but shows an error in the console:

[DecimalError] Invalid argument: banana

What I would like is a way to include ranges in the destination specification. Eg <!-- TBLFM: @>$2..$3=sum(@2..@-1) -->
