Timer default interval configuration

Hello.

Whenever I enter the timer function on my Forerunner 55 the default interval of 5 mins is proposed. Since I am normally (everyday) interested in running a timer for 20 mins, then I have to change it every time (which is quite annoying).

Isn't it possible to set somehow the default interval proposed by the timer function? Or, at least, isn't it possible to configure the Forerunner for "remembering" and "re-proposing" the last interval that a timer was started with?

If something like that is not possible at this time, isn't it possible to consider such a feature for a future Forerunner SW version?

Thanks + regards.
