Yes, and the ease of which is determined by how your db table is set up. Here is a generic example of how it could look:

local ACR = LibStub("AceConfigRegistry-3.0")
local ACD = LibStub("AceConfigDialog-3.0")
local LSM = LibStub("LibSharedMedia-3.0")

local anchorList = {
	TOPLEFT = "TOPLEFT",
	TOPRIGHT = "TOPRIGHT",
	BOTTOMRIGHT = "BOTTOMRIGHT",
	BOTTOMLEFT = "BOTTOMLEFT",
	LEFT = "LEFT",
	TOP = "TOP",
	RIGHT = "RIGHT",
	BOTTOM = "BOTTOM",
	CENTER = "CENTER"
}

local unitFrame = {
	Player = PlayerFrame,
	Pet = PetFrame,
	Target = TargetFrame,
	TargetTarget = TargetFrameToT,
	Focus = FocusFrame
}

local unitList = { }
for unit in pairs(unitFrame) do
	unitList[unit] = unit
end

local db = { }
for unit in pairs(unitFrame) do
	db[unit] = { }
end

local selectedUnit = "Player"

local function GetOption(info)
	return db[selectedUnit][info[#info]]
end

local function SetOption(info, value)
	db[selectedUnit][info[#info]] = value
end

local function UpdatePosition(unit)
	local frame = unitFrame[unit]
	frame:ClearAllPoints()
	local settings = db[unit]
	frame:SetPoint(settings.point or "CENTER", settings.relativeTo or UIParent, settings.relativePoint or settings.point or "CENTER", tonumber(settings.offsetX) or 0, tonumber(settings.offsetY) or 0)
end

local function UpdateStatusBar(unit, barKey)
	local settings = db[unit]
	local statusBar = unitFrame[unit][barKey]
	statusBar:SetHeight(tonumber(settings[barKey .. "Height"]) or 12)
	statusBar:SetStatusBarTexture(LSM:Fetch("statusbar", settings[barKey .. "Texture"]))
end

local function SetStatusBarOption(info, value)
	SetOption(info, value)
	UpdateStatusBar(selectedUnit, info[#info - 1])
end

local testOption = {
    type = "group", 
    childGroups = "tab",
    name = "TestOption",
	get = GetOption,
    args = {
        selected = {
