There is no smarter way,No.Preta's path carelessly absorb all sennin mode's chakra.He might could absorb chakra better,but not in absorbing it in a smarter way.
Kisame as well takes this in terms of chakra-absorbing usage.
*Facepalm* Pein didn't know sage chakra would turn him into a statue. And neither would Kisame who has never fought someone in sage mode. So I'm pretty sure he would try to absorb his chakra too.No.Preta's path carelessly absorb all sennin mode's chakra.He might could absorb chakra better,but not in absorbing it in a smarter way.

For one thing Samehada is more like a living organism and it can crawl so it can move it crawled to where bee was. And Kisame absorbed Bijuu chakra without knowing what it would do to him. And Nagato didn't try to absorb Jiraiya's chakra as he did with jiraiya's as naruto was constantly gathering sage chakra which made the path unstable because he didn't know how to control it. In the end Preta path > Samehada and KisameI don't call Nagato being smart absorbing sage mode chakraYou must be registered for see linksFundamentally,he knew about sage mode from his experience with Jiraiya.Nagato must've known the basisYou must be registered for see linksandYou must be registered for see linksof senjutsu.
As the former wielder of Samehada,Kisame is very keen and a good simulator fromYou must be registered for see linksIt's not wrong to say he wouldn't be careless absorbing overmuch sage chakra.
Also,I'm referring to Kisame using Samehada since the sword itself couldn't move without someone handling it.
Same as Preta Path,it can't react on it's own,there's have to be someone to become the 'jinchuuriki' of the path.
