eVar allocation and expiration is controlled from Analytics. The closest you can get to that is targeting past behavior based on the eVar allocation setting.
Here is what you woudl do:
1. Ensure that Expiration and Allocation are set to whatever you need them to be in Analytics.
2. Set up an Analytics audience around the eVar in question.
3. Accept the reality that Analytics audiences are not indented to used for immediate targeting. For that Taret native audiences are best. (More on that here:https://helpx.adobe.com/marketing-cloud-core/kb/People/Audience-Creation-Options.html make note of the "Audience Becomes Actionable" row in the "Audience Creation Options" table)
4. Share the audience to Target for use in targeting past behavior on the site.
A better option:
Would be to work with an Adobe implementation consultant to deploy additional code on the site that sets the value for a user's profile parameter to something specific when the eVar's value is whatever you are trying to target. You would then build a Target Native audience around a profile script that looks for that specific profile value. This will give you a way to immediately affect change on the live site when the specific eVar value is triggered.
As a separate point if you have Target Premium you will have access to XT Experience Targeting activities. This is the only activity type where it is possible for the end user to move from one experience into another based on matching different audience requirements.
