Merging 2 Business Listing Possible?

I have 2 verified listing on my account.

Business 1
Business 2

Business 1 have around 1k reviews and Business 2 and only 50 reviews. I want to merge both and want to show Business 1 and reviews should also be added which means (1000 rev + 50 rev) 1050 review.

I want to know, what is the procedure to do that?

Or is there any other solution?

There is no way to add them together.
You can change the name of the other one or delete it.

There is no method for combining two accounts, so maintain the highly reviewed account active and alter whatever you need to.

You can request Google only if the 2nd one is duplicate of 1st one otherwise it is not possible.

------ UPDATE ------

Both Google Listing has now merged. Now only one listing is showing, all 50 revs of 2nd listing have also been transferred to listing 1. What did I do? I asked the same question on Google Business Profile Community and an expert suggested me below steps:

1- the first step is to rename Business 2 to the exact same name as the other business listing 1
2- Then Delete the 2nd listing from your account and (I didnt do that till yet)
3- then in Maps make the edit the Business 2 and mark as a duplicate of business 1 (I didnt do that till yet)

It is possible to do this, you can get support from the Google Help section.
