As far as I know, it wouldn't be an exchange as such, but a cancellation of your 4-day Swiss Travel Pass and purchase of an 8-day Swiss Travel Pass.
For the cancellation, you will usually only get a refund of 85%, but it would still be cheaper to do this and get an 8-day pass rather than getting an additional 4-day pass.
I can't say for sure, but I would expect that only the company that issued your 4-day Swiss Travel Pass would provide you with a refund.
You could buy your new 8-day Swiss Travel Pass in Switzerland at any staffed railway station (or from the same place you bought your 4-day pass).
