How to merge multiple variants into the same CNV?

Structural Variation
1

For example, 4_DUP, with 108 individuals carrying this variant.The position of 4_DUP is Position[1:925634-966359],and the vcf file shows POSMIN=911848;POSMAX=948034;ENDMIN=939558;ENDMAX=982191.
I am curious about how to integrate the variant ranges of these 108 individuals into the final result, and how to confirm that they belong to the same CNV.
