Different menu items at top of page

[cdmcdermott]

Is it possible to have different menu items at the top of different pages?

Page 1:
item1, item2,item3

Page 2:
item1, item3, item4

At the moment I just specify the same menu items for all pages in config.yml

menu:
main:
- identifier: item1
name: item1
url: /item1/
weight: 10
- identifier: item2
name: item2
url: /item2/
weight: 20
- identifier: item3
name: item3
url: /item3/
weight: 30
- identifier: example
name: example.org
url: https://example.org
weight: 30
