How to clean history / protocol from Redirection Manager?

I switched from other plugin to Redirection Manager.

How can i clean the protocol / history. e.g. it shows redirect was used 35 times / last date … > How to delete this table. I dont want to delete redirect, just the protocol.

Reason: i use Adwords. When i see a redirect has many uses, i check my campaigns and change to new url. After checking all, i want to clean table, so that one week later i can see if there are new entries with higher volumes.
