Dynamically change the search help selection fields

Hi,

We have a quite different requirement, where Architect wants to design some thing like below.

Have a search help assign to material(existing standard MAT1) which have field list like this.

mara-matnr, makt-maktx, lfa1-emnfr, reference field name, field value.

The intention is to have a CDS as selection method, which will be liked to multiple union accross different tables.

On the fly, field name and field value can be picked.

I can see, SAP has field field list for every search help. So if this is possible to dynamically pick the fields?

Any help is appreciated.

Thanks,

Sumit.
