Hello,
01. Sorry, but there is no option available for that in Theme Settings.
It requires customizations and this is beyond our limitations and support policy.
02. Try to use a custom label for this. To display a custom label, you can achieve this by using attributes.
Follow these steps:
1. Navigate to Products > Attributes, then edit the desired attribute.
2. Enable the option to display the attribute label on the product image.
Next, add this attribute (which includes the label) to the products where you want the custom label to appear.
Once the attribute is added to the product, the label will be displayed on your website.
03. You can add more text in the form of a short description, Navigate to Theme Settings > Product Archive > Product Styles > Choose the “show summary on hover” product style. Then show “excerpt” in the Hover content in the Theme Settings > Product Archives > Product Styles.
This product style will show your short description on grid products.
