Yes, cells in Clay can contain lists of items. You can use the Write to Other Table feature to map each item in a list to individual rows in another table.
This is useful for "flattening lists" - for example, if you have multiple location IDs in a single cell, you can send each location ID as a separate row to another table using the "Send row for each item in a list" option.
Hey there! Happy to look into this - where is the data pulling in from? I don't see a native Clay source attached here, but you should be able to add a new column with a secondary Location ID or merge the two into a 'list' (e.g. 1231323, 1231234)
all the values already inside of the column before importing, so you can add more location ID values here however this will either be done manually, if this was data imported from another source then this may be a bit harder to do, as the column where this value is coming from needs to have all the values already inside of the column before importing
