Ho to set a choice of units in the backend

Hello!

Most of my products are sold at a "per unit" price, however, some specific products are sold in packs of 4, so the word "each" which follows the price confuses my customers. Is there any feature in the free HikaShop version to choose between two custom units (could be "XX.XX$/each" and "XX.XX$/package")?

I though maybe custom fields could help me achieve that (if I buy the "Essential" license), by inserting a particular custom field I could name "custom_unit", inline right after the product price (and hide the default unit text), would that makes sense? And could I have the possibility to display other custom fields in other positions in the template if needed (let's say after the product description) or then all other custom fields will be placed after the product price too? I went to the Hikashop demo (backend) to verify if it would be possible, but it's hard to tell..

Thanks!

As I need to display an the unit after the price, the translation override doesn't work for me, but I'll consider buying the Essential version to use the custom fields. Thank you!!
