Change next page numbering to words

Hi all,

Anyone know how I could change the next page numbering at the bottom of the landing page from numbers to words?

eg: at the bottom of https://preview.metricthemes.com/marinate/

there is 1 2 … 4 >

I’d like to change 1, 2, 4..etc to words (which are unique)

THanks,

Ray.
