Merging VCF files


I am hoping someone can give me a tool recommendation for the following task.

I have generated multiple vcf files and now I want to combine them into one, while eliminating duplicates (variants present in more than one file). However while doing this, I also want data on how many files a given variant was present in.

As far as I know tools like vcf-merge, Combine Variants etc does not provide this information. Is this possible?

Any help is greatly appreciated! Thank You.
