So I just got off a ticket with Epicor.
Apparently this is a known issue. (that is the import reports checkbox missing). Still waiting on the problem number. And really by design
In SSRS after you deploy all you get is the shared datasource.
It appears the default RDLs get stored in the ICECommon_4_3_100.Ice.ReportStore table (yes there is a new read only db. I saw it in 2023 also.
In an attempt to deploy the reports to SSRS I took a look at the SetupData.xml file in the C:\ProgramData\Epicor\SetupInfo. I noticed that the SSRSReportDirectory key is empty, compared to 2023.2 it has the paths of the reports.zip file from the installation directory. I populated that and set the SSRSImport flag to true… It sort worked, only creating the Obsolete Stock Report and the PaymentProposal report. 
Going to do a full reinstall again and see if I can get it to work.
EDIT
No reinstall required. It appears to be by design. No import of RDLS needed to the SSRS Server.
It seems to be that you can’t use the classic report style form to copy a report style. You can in the Kinetic UI. This will be because of the lack of the RDLs residing on SSRS. (New installs only).
@josecgomez I think your SSRS migration tool has met it’s match. :(.
That being said, I am guessing an updatable dashboard would work. @aosemwengie1 Looks like being able to copy your custom reports from one environment to another, just got easier 
I am a little frustrated that they have broken classic report styles. but at least there is a work around. Just another reason to go Kinetic UI, I suppose
