In LastPass Authenticator app add the ability to have similar services (sites) grouped together. This will reduce the length of scrolling if someone has multiple accounts from the same service.
For example if I have 5 different google accounts, have all google accounts grouped together and then to access the specific google account for the 2FA TOTP code one would click on Google and it would expand a list of all the google services.
This can be a grouping option, default grouping could be how it is right now, then group by service is another group option. Add feature to group services in LastPass Authenticator. As an extra if the ability to color code accounts was added then grouping by color code can also be benificial.
Bonus suggestion: As an extra if the ability to group services in catagories was added like how it is in LastPass Pastword Manager then grouping by catagory can be an option.
