How to prevent Content Builder plain text from designating the same link to an AMPscript variable?

The AMPscript is set up like this in Content Builder. Example:

Content Block 1SET @linkButton = "link1.com"Content Block 2SET @linkButton = "link2.com"Content Block 3SET @linkButton = "link3.com"

In the plain text only, "link3.com" is displayed for every @linkButton instance since that was the last link assigned to the @linkButton variable. Are there any workarounds for this without assigning a unique variable name to each link?
