Save specific attachments via outlook

im trying to automate email attachments download via Outlook
every day i’m getting a mail with a lot of attachments (all of them are .xlsx) and i only need 8 of them.
i can filter the “save attachments” activity for each of these 8 files(8 times), but maybe in future i will need to download more file or less files and i don’t want to rewrite the code every time

what is the best and efficient way to get only those 8 files to download?

Store the value in a variable and use the variable as an asset in orchestrtaor, or you can give it in the Configuration file if you are using RE framework
