use of mail app

hello,

i want to use, once catalina is installed on my iMac, the mail app from apple in place of the 32bit app in use now(not supported anymore). I have a lot of rules to select mails and put them directly in the correct mailbox when received and i have defined these rules in the mail app on my iMac. is it not possible to transfer these rules on my iCloud to share these rules with my macbook air?( Like in notes where you can transfer easily notes from iMac to iCloud to share !) I didn't find any option in the mail app to do it easily .... or only redefine everything in the iCloud !!!!

Should this option not be available on the mail app as for the notes app?

with kind regards,

JP V.
