Retain position on continuous form through requery

Question

I have a continuous form that, for reasons of efficiency, must use an underlying query that groups records and provides totals. Therefore, the underlying recordset is (correctly) not updateable. However, I do need to flip the value of one of the (header)
fields from True to False or False to True. So I have a button in the detail section of the form that checks the current value, creates the SQL statement to change the value, and runs the SQL statement.
So far, so good. Now, to get the new data to appear, I must requery the form, but that, of course causes me to lose my position on the continuous form.
So I set a variable to the value of the current PK in the header table before my requery, then use Bookmark to return to the record that was current before the update & requery. Again, so far, so good...except for one thing.
The user may have the current record in any vertical position on the visible part of the list. That is, the record being edited could be at the top of the visible records, the second one down, etc, or even the last record visible (I have a vertical
scroll bar). Using Bookmark returns me to that record, but it automatically places that current record at the top of the visible portion of the record list (form's detail section) after the requery. This is quite confusing for the users, and they can
easily lose their places.
Is there a way, not only to return the current record after the requery, but to return that record to the same vertical position within the form's records in the detail section so that there is no apparent jumping around?

Hi Brian
D. Hart,
In early 2000s I published the solution here:

That sample isn't English localized. That's why I redesigned it for you. You can download the ajusted version from here:

By the way, the key moment of it was discussed early here:
