[Feature Request] Improve usability of datamap etc

[frsommer]

Is your feature request related to a problem? Please describe.
@Freymaurer Handling of datamap description is quite un-handy, i made a testARC adding issues which could help for improvement. here is the Arc and below the points once more (with pictures in the testARC:

https://git.nfdi4plants.org/frsommer/TestARCfred

1. some data columns contain combined results from 2 files (example row 1+4, etc...), these must combined. not possible with the annotator tool. can select the columns and copy paste in the additional rows. but the problem is that it then forgets the col number, so have to add it manually.

solution:
would be cool if the complete cell (or whatever is adjoint to it) is included when copying/pasting.
or when the columns could be clicked multiple times and are inserted in the order of clicking

2. sometimes main results are in multiple files, a second "Output [Data]" cannot be added. that's why i added a second sheet (TestOUT2) (export assay and import again, would be cool if it was possible to just dulpicate the sheet with a single click).

3. in the DataMap it is not possible to add columns from 2 different files (workaround would be a new assay, which would be a pain. second datamap would be a solution but not so nice in some cases).
   would be good to have this possibility (adding rows and marking them, then filling marked rows with the datamap tool, e.g)

4. btw the datamap cannot be viewed in the arcitect so i put it as xlsx in the assay -> protocols

5. would be very nice if the headers of the chosen columns in the datamap would be already imported in the Label field

6. please add the copy paste functions in the datamap, it is killing me pasting the txt from my excel in each individual cell

feel free to edit delete or share the arc
thx and cheers fred
