It is not possible to have multiple page properties macros on the same page with the same label and report them on the same page properties report macro

Hi, I am trying to have 3 page properties macros in different sections on 1 page. They all have the same label. I would like to collect all data in 1 page properties report. If I understand the documentation well, this should work (as long as the labels are the same). However, it seems that only the last one or the one in the righthand section is included in the report. I have tried without mentioning the column headers and with mentioning them. In the latter case, no values are displayed for the columns that do not belong to the last page properties macro. In the first case, only the columns belonging to the last or the right-hand macro are included. Please, advise.

Current functionality is that when there are multiple Page Properties macros (with the same label specified) on a page the Page Properties Report macro only reports the data contained in ONE Page Properties macro in the report.

Steps to reproduce:
1. Create a page with a page properties macro. In that macro, add a table that looks like this:

2. In that macro, give it a label 'prop1'
3. Add another page property macro on that page, give it the same label 'prop1' with the contents:

4. Save the page. Now create a new page in the space.
In that new page, create a page properties report macro and give it the label 'prop1'.
Outcome: It reports on ONE table only (c and d)
This feature request is so that it displays all data (a, b, c and d) because the label 'prop1' is specified on both.

This appears to be the reverse of the use case in https://jira.atlassian.com/browse/CONF-28776
