Evaluate the revision - Set the value of the Additional product field through the menu of mass changes

those. we take the existing block, where you can select only 1 field that is displayed in the bulk changes menu, and add to it the ability to choose which additional field we want to change. This is interesting to me, since every day changes are made in additional fields with discount dates, and it is necessary to keep as many as 6 such blocks for these sites.
at the output, for example, we have a block in which we indicate in advance which additional fields we can display in it for selection already in the menu of mass changes of the DPP.
and then I can make such a block where, for example, a choice of 3 additional fields discount value (change it in bulk to the specified one)
and the Discount date block, where by selecting the additional field Discount date "site" from or to I can specify a new value (date) for it and overwrite it in bulk.
for me it makes sense to divide into types of additional fields for convenience, but the question is, if in the preliminary multilist there are fields of different values: number, text, date - is it possible to change their value and add them to one multilist? or it will be necessary to separate them by type: Number, tex, date ........
I'm interested in this, the functionality will facilitate the work and reduce the trash in the menu, now it looks like this for me https://prnt.sc/107ucl2

it will be a new block with similar functionality, but taking into account field types

I need a drop-down list, the ability to select 2 blocks is not suitable, so you can make a big mistake with this action if you chose 2 additional fields to change

in my opinion, there was a misunderstanding here, the screenshots show the same block, 1) its settings, 2) and 3) how it will look when choosing additional fields of different types, for example, a multi-list of products and dates
