Global Variant for Query

I am on BI7.

In Query Designer, I have created a Variable for each of the Characteristic on my query.

when I run the query, I can now enter the parameter for each of this Characteristic and Save it as Variant.

When I run the query again, I can select this Variant. No problem, working fine.

However, when my colleague run this query, he/she can't see this variant.

How can we create Global Variant so that all user can use it?

Please help, thank you.
