Search option for Custom Field LOV/Smart Search

Summary:

Under SM Header and Edit Product page we have custom fields

We experienced the difficulty to fill in the customer segment and manufacture code from the list under Subscription order.

whether order header or product page, it's difficult for us to select the account from the list, sometimes we can't find it because the ordering is incorrect, and there is no way to search it if we don't remember the required details

is it possible to change that LOV type with search option, below is the screenshot which shows the current LOV type for the custom field, there is no search option users have to scroll through the LOV to search the values which is way inefficient. is there any way to change this
