use Title Tag as short product description

Currently using the Storefront theme with woocommerce.

I looking for very short description that I can display with products on the shop page.

Currently I display the ‘short description’ for each product but this is becoming somewhat lengthy (can be 7-8 lines of info) and would like to use a ‘small description’ say the ‘title tag’.

OR is there a ‘small description’ field I could use.

Is this possible and how would I do it.

Thanks
