Wordpress question - can you do multiple schedules for a single page?

I've got a page on one of my blogs I wanted to TRY and schedule multiple updates on.

Is it possible?

What I am thinking is this (described as best as possible)

Say I have an "about" page

Today I posted a line of text i.e. "this an about page"

Now in a weeks time I want that page to add some more text i.e. "here is some more text"

So on week 2 it will look like "this is an about page here is some text"

On week 3 I want it to add more text "and here is an update"

So on week 3 it says (you get the point)

Is this possible? I want to sequentially cue pieces of text on a single page to update once per week. Kinda like scheduling posts but all on one page.

I haven't tried this yet or seen anything about it so guess it isn't possible but it's always worth asking incase

Thanks for any ideas/suggestions.

P.S. it doesn't matter too much to me I can obviously add this little update every week myself, automation is just a bonus
