Overwrite the same news source file

[dmac]

​Hi,
I have a quick question that I cannot see in the forums or docs about caliber.

In fetch news, I have a news source set to run daily at 6am.

After it completes and syncs with my device, is it possible to set it up so that it overwrites the same news source file that is on the device every morning, instead of show the new file added each day?

i.e. Always have the same file overwritten, and not have multiple daily files (with the same name).

Thank you.
