Is there a way to manually set the time position of an AnimationTrack during interpolation?

So the title pretty much explains what I am asking here - I've made a simple animation that plays when a character fires a gun in my game, but the problem comes with how the default animation interpolation system plays the gun firing animation a little bit too slowly which makes it feel less "powerful", as firing a gun should feel. I have tried looking around on the wiki for a way to set the time position of the animation to a specific keyframe without having to wait for interpolation, but I couldn't find anything.

I wish I could show a couple of Gyazo GIFs to demonstrate the problem, but unfortunately this website doesn't support Gyazo (if there is another way to upload GIFs please let me know). So if it hasn't been clear so far, what I'm looking for is something similar to a CFrame:lerp(goal, 0.5) function where you can manually set the time position of the interpolation but for AnimationTracks made with the Roblox animation editor.

When an AnimationTrack's Speed property is equal to its Length property, the track will be 1 second in length. That being said, you can divide the length by the amount of seconds you want the animation to play to adjust the speed accordingly. You can change an AnimationTrack's speed using the AdjustSpeed method. Taken from here:

function playAnimationForDuration(animationTrack, duration)
	local speed = animationTrack.Length / duration
	animationTrack:AdjustSpeed(speed)
	animationTrack:Play()
end

You also don't have to call AdjustSpeed every time you want to play the animation, it can be done after your LoadAnimation initialization in the global scope. i.e

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:wait()
local humanoid = character:WaitForChild("Humanoid")

local tool = script.Parent
local animation = tool.Animation

local track = humanoid:LoadAnimation(animation) --load the animation into the humanoid
track:AdjustSpeed(track.Length / 0.5) --this track will last for half a second

tool.Activated:Connect(function()
	track:Play() --play the animation when the tool is activated
end)

Hope I helped!
