How do I add to a metaobject list while retaining the previous list items?

[impertiknits]

So far, if I update the metafield (which is a list metaobject) with the following as the value, and the existing value of the metafield is blank, it will work tickety-boo, no trouble:

["gid://shopify/Metaobject/26233635050","gid://shopify/Metaobject/26233733354"]

However, if the metaobject list already has a value, it will overwrite it and lose the original values.  Is there a way to retain that information and simply add to it?

Thanks for any help in advance!

Yes, you need to merge those new metafield values with the existing values. You can do that using "Run code" or using Liquid in the action. There are a few threads that show how to handle merging lists, like this one: https://community.shopify.com/c/shopify-flow-app/how-can-i-convert-product-tags-into-metafield-singl...
