Help me get my companion out of the way

[Hopea]

So, I have this what effectively is a combination of cohort and Eidolon. But thats not the point.
The point is, I want some way of storing them away for when its not needed (main reason being because its slow and I cannot yet afford to significantly up its speed)
I found this

but it needs a summoner specific ability, and while I have the eidolon, I'm not a Summoner nor do I have access to Summoner abilities (what I do have is a very cool GM).
So, tips, ideas? 3rd party and older edition stuff is ok too.

Maybe you can give us the specifics of your situation? If you have an eidolon, cant you just dismiss it? Is it actually a physical native creature who had eidolon like abilities? Are you a spell caster? What kind of spells do you have access to? How slow is this thing that it can be useful in encounters or other difficult situations (and thus you want it to come along) but moves too slowly to travel?

I don't know, but its a minute to summon it even if I could.

Are you a spell caster?
I'm a Wilder/Psion Uncarnate 6/4

What kind of spells do you have access to?
Psionic Powers up to 4th level on the Psion/Wilder list and up to 3rd on other lists.

How slow is this thing that it can be useful in encounters or other difficult situations (and thus you want it to come along) but moves too slowly to travel?
20 ft. Its also about having to move its token all the time. And its not really that useful in dangerous situations, its our walking multitool.

If its humanoid shaped maybe have it ride a horse?

Its a serpentine form. And I really don't need more things to track, especially things a fireball can drop accidentally.

I did find the hostelling armor property. That could work (Manifesters don't have spell failure from armor)
