8 times faster? I would like to challenge that statement 
Unless you mean recording ALL eight sliders - that would be a suggestion, yes. There is a tool however that does something closely related…afta8’s Snapshot

Here, you could simply choose when to “snapshot” all the doofer/macros parameters. It’s a quite handy tool and better than polluting the automation system with numerous unchanged values (if I understand your suggestion correctly)
But back to the topic of “i’m getting tired of entering all the pattern effects one by one”:
The Doofer, well that’s just a question of right-clicking to record automation - graphical or pattern effects, depending on which Automation record settings you have chosen. You know, that little icon in the pattern editor toolbar that can look like this 
(pattern fx)or this 
(envelopes)
Same is true for the Macro device - but here, you need to insert it into a track first.
This is necessary since instruments are not hard-linked to a track in Renoise - without the macro device, there would simply be no track to record the automation into.
Sorry if I’m being a little over-obvious here, but someone might read this and pick up a few tricks
