Can we change user's reminder after it has been set

[kishan-getstarted]

we are working on the platform where a non developer can create alexa skill by drag and drop. we are providing reminder block so producer can set that without coding.

My question is once my skill is live and lets say 10 user has created reminder using my skill.. can I update those reminder using SMAPI or any SDK

we are storing alertToken and alexaUserId in our database.
