Is there any way to merge two saved searches
Not that I know of. This may one day be possible through the analytics function, but currently isn’t. You can build a search that will show all SO’s and show any associated Return Authorizations through formulas, but if you have Return Authorizations not associated with SO’s, you’re out of luck as they wouldn’t be pulled into that. Your only option then will be to download to CSV and merge via excel.
No – It’s not possible yet with standard functionality. Marty zigman has a blog that goes into how his firm get around this. through his ‘Dataverse’ idea and their content renderer engine.
They don’t offer these to external users though – only their own clients.
