Change custom field dropdown (type = list) using value (text) instead of idValue

Is it possible to change a custom field dropdown list of a Trello card to a different value by using the text of that value and not the id of that value?

With below example it is possible to change the value by putting idValue=“5a6a23abf958725e1ac86c22”
I would like to do the same but not with the idValue but with the text behind this idValue

Setting & Updating CustomFieldItems:
curl -X PUT -H “Content-Type: application/json”

-d ‘{
“idValue”: “5a6a23abf958725e1ac86c22”,
“key”: “”,
“token”: “”
}’

This isn’t possible for a dropdown. The could do this if you changed the type to a string, but then you lose the validation of the dropdown items.
