# 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 %}

## Merge existing Value Sets

Merging can be accessed from![](https://content.gitbook.com/content/ecIrdZnsDkSPypTQNKj0/blobs/qVavUpZlpLETGMwsmjvM/actions_button.png) in editing mode only. 

The merge process can be started by selecting the *Merge value sets* option, which will open the merge wizard where the Value Sets to incorporate clauses from can be specified.

No new Value Set will be created, but clauses from the selected Value Sets will be added to the one that is being edited.
