# Merge

Snowray enables merging the content of one Value Set into another. Clauses from the *Inclusions* and *Exclusions* sections of the selected Value Set will be added to the corresponding sections of the target Value Set.

{% hint style="info" %}
For now, only three Value Sets can be merged into another one at a time.
{% endhint %}

Merging can be accessed from![](https://content.gitbook.com/content/mtqpPjWCd58lq3KcPQAE/blobs/Xc1Q7Boqkq2ktLEYRpG2/actions_button.png) in editing mode only. The merge process can be started by pressing the action menu item called *Merge value sets*, which will open a new window where the Value Sets to merge clauses from can be specified.
