如何在运行时更改discord.py中tasks.loop的间隔

我正在尝试制作一个机器人,提醒人们每隔几个小时喝足够的水。我试着用任务来做这件事,但意识到我不能让用户决定时间间隔,因为当你启动机器人时,循环的时间已经初始化了,不能再更改了。

我看到的解决方案只使用睡眠而不是任务,但这些解决方案阻止了机器人在运行时处理任何其他命令。我目前的解决方案是有5个不同的循环可以切换,但在我看来这不是一个很好的解决方案。这就是现在的样子:

@client.command()
async def w(ctx, t = None):
    global w
    global channel
    global ti
    
    if w:
        if ti == "3":
            water3.cancel()
        elif ti == "1":
            water1.cancel()
        elif ti == "2":
            water2.cancel()
        elif ti == "4":
            water4.cancel()
        elif ti == "5":
            water5.cancel()

        w = False
        await ctx.send("The water reminder is turned off")
    else:
        channel = ctx.channel
        message = "The water reminder is turned on"
        ti = t
        w = True

        if t == None or t == "3":
            ti = 3
            water3.start()
        elif t == "1":
            water1.start()
        elif t == "2":
            water2.start()
        elif t == "4":
            water4.start()
        elif t == "5":
            water5.start()
        else:
            message = "Invalid command: Please choose a number from 1 to 5"
            w = False
        
        await ctx.send(message)


@tasks.loop(minutes = 3)
async def water3():
    await channel.send("Remember to drink water")

@tasks.loop(minutes = 1)
async def water1():
    await channel.send("Remember to drink water")

@tasks.loop(minutes = 2)
async def water2():
    await channel.send("Remember to drink water")

@tasks.loop(minutes = 4)
async def water4():
    await channel.send("Remember to drink water")

@tasks.loop(minutes = 5)
async def water5():
    await channel.send("Remember to drink water")

它有效,但我不喜欢。一定有更好的方法可以做到这一点,对吧?
