Cursor filter for range between 2 custom field values

-- HikaShop version -- : 3.0.0

Hi

I would like to make a filter, where the user can filter using the cursor and set a single value, and filter based on 2 custom fields that contains low and high value.

E.g. room size. A product could be ideal for a given room size, e.g. between 50 - 95 m2.
I have such 2 custom fields on the product.

I would like to have a cursor, that I could set to e.g. 75 and only display the products where 75 is within the range of my low and high fields. Makes sense?

Is this possible in any way?

Another thing - cursor number seems buggy - no matter if I set it to 1, 2, 3 or 4, it always displays 2

Thanks
