Play Sample From Selected Position Via Keyboard

It’d be cool if you could first select the position from where the sample would be played and then key jazz with channel effects in sample editor. Now when you keyjazz the sample always starts from the beginning. You can only play samples from selected position with a mouse click and if you want to play from different note you’ll have to click the note buttons with mouse but still you can’t hear the channel’s effects where your pattern view cursor is at. Playing sample from selected position would be really handy when you have long samples and want to hear how they sound with selected effects. Am I missing something?
