Can we have a separate storage in RTC for attachment?

Hi,
We are currently using ClearQuest (CQ) for defect management. For most of the records we have some attachments which are of huge size. Sometime more than 500mb.
Our team has designed CQ such that the attachments are getting stored in a different file storage system.
Now we want to migrate defect management to RTC.
Is it possible that we can have a similar/separate storage system where attachments can e stored?
RTC 6.0.2
Accepted answer

There is nothing available in RTC today. This would be a useful enhancement request here: https://www.ibm.com/developerworks/rfe/execute?use_case=changeRequestLanding&BRAND_ID=0&PROD_ID=435&x=24&y=11
It might be possible to create an extension (follow up action that transfers an attachment to another system and creates a link in the work item. I am not absolutely sure of that.
