Currently, in InSearch, in order to make a selection for a 'standard' item (something included/requires no payment or upgrade to select) you must create an option in the IHMS database so that you can 'select' that standard item. This is different from the 'normal' operation of IHMS where you can use the color selection items (color sheet/selections sheet) to make your 'standard' selections.
We created this functionality in our database, previously, when we created our color sheet so if this is something that insearch is willing to do - reach out to me to discuss.
