AB Posts/Page Block - Display more than 4 columns horizontally

[cre8tivediva]

Is your feature request related to a problem? Please describe.
The setting only allows for 4 columns.

Describe the solution you'd like
I actually need 6 especially when in full width mode with smaller thumbnail images.

Describe alternatives you've considered
I cannot find another solution unless I use Featured Posts widget along with the Shortcode for Widgets plugin where I can add the shortcode in a block and set it to 6.
