Sugarcube 2: Avatar in Sidebar

I want to assign every player a random avatar at the beginning of the game. This assigned avatar should then be seen in the sidebar.

So I would write for example on the start page:

<<set $avatar to either ("[img[ava1]]", "[img[ava2]]")>>
<<remember $avatar>>

Your avatar is $avatar

and in the special passage StorySubtitle just:

$avatar

1. Is this the perfect solution in the first place?
2. What if I would like to assign the avatar on the start page, but first show it in the sidebar on the second page?


thank you in advance!!
