Sentinel3 Synergy product tile based search

I have a files of almost covering same extent:
i)S3A_SY_2_SYN_20210528T0509331_20210528T051231_20210530T041715_0179_072_176_2340_LN2_O_NT_002
and
ii)S3A_SY_2_SYN_20210601T050547_20210601T050847_20210603T053128_0179_072_233_2340_LN2_O_NT_002
I want to download time series of sentinel3 SYN products with same extent, from Copernicus data hub (https://scihub.copernicus.eu/dhus/#/home).
I have referred the file naming scheme (User Guides - Sentinel-3 Synergy - Naming Conventions - Sentinel Online - Sentinel Online).
The documentations says that one can use [ instance ID], based on this we can say that
for product details are as follows
i) Product tiling type: FRAME, Duration of acquisition=179, cycle number = 72, Relative orbit number = 176,
Along track coordinate = 2340.
and
ii) Product tiling type: FRAME, Duration of acquisition=179, cycle number = 72, Relative orbit number = 233,
Along track coordinate = 2340.
I am thinking of meeting the objective using the relative orbit number or perhaps Along track coordinate, but I am not sure because there are other files wherein I noticed that identical Along track coordinates with frames covering different geographic extent.

From file name, which parameter should I use, if I want to download frames corresponding to the same extents? Is there any shape file or kml file that I can use to get the template of such a parameter?

I would suggest that you contact the support of the data hub.
I think they can help you better.
In theory the the ID should be sufficient.
It maybe the start and stop time helps. This should be unique too.
But I think the support can answer your question better.

alright. will send email to eosupport
