How to reset the timelines without giving wrapmode to none

Hi I have sequence of animations in my use case I am trying to achieve it via timelines
Here I have taken two timelines for two steps 1 .One first button click one information panel popup will appear along with it second button will appear and first button disappears (wrap mode : hold)

2.When click on second button animation of an object will happen, at the end one info panel will appear and the second button appears as first button appears (wrap mode : hold)

Issue : The whole sequence is working fine in first attempt when tried it in second attempt things are not getting reset.

Is there a way that I can reset it via timeline (without giving wrapmode :none ) or I should manage it via script ??
