There's not on Standard, no.

I execute a stored procedure prior to the RS Execution, which another one of the DBAs we have made, which is as follows:

Create Proc [dbo].[UpdateRSOutputFile_sp] (@NewFileName varchar(100),

@ReportName varchar(100)) as

--ReportName = Name of report as show on server

--NewFileName = Desired new name for file. Exclude file Extension if you are automatically including this via the subscription settings.

UPDATE ReportServer..Subscriptions

SET ExtensionSettings = Left(cast(ExtensionSettings as varchar(max)),cast(CHARINDEX('FILENAME',ExtensionSettings) as int)+21)

+ @NewFileName +

right(cast(ExtensionSettings as varchar(max)),len(cast(ExtensionSettings as varchar(max))) - len(left(cast(ExtensionSettings as varchar(max)),len(LEft(cast(ExtensionSettings as varchar(max)),cast(CHARINDEX('FILENAME',ExtensionSettings) as int)+21)) + cast(CHARINDEX('</',right(cast(ExtensionSettings as varchar(max)),len(cast(ExtensionSettings as varchar(max))) - len(LEft(cast(ExtensionSettings as varchar(max)),cast(CHARINDEX('FILENAME',ExtensionSettings) as int)+21)))) as int)-1)))

FROM ReportServer..[Catalog] C

join ReportServer..ReportSchedule RS on C.ItemID = RS.ReportID

WHERE RS.SubscriptionID = Subscriptions.SubscriptionID

AND Name = @ReportName

and DeliveryExtension = 'Report Server FileShare'

Note that if you have a report with multiple subscriptions, this'll update them all. It's not an issue for us 9actually it's an advantage), but if you don't want it to do that, you'll need to make an amendment to ensure you update the right one.

Hope that helps.
