Show prices with tax/without tax toggle

-- HikaShop version -- : 4.7.47
-- Joomla version -- : 3.10.11
-- PHP version -- : 7.4.33

Is there a way to have a toggle at the top of the page (as a module) which can be toggled to show prices with and without tax?

All prices are shown on the page, but then then style is updated.

For example, when the toggle is set to show prices with tax, the style would be:

<div class="productPrices">
<div class="priceswithTax bold">£120.00</div>
<div class="priceswithoutTax">£100.00</div>
</div>

the if the toggle is set to show prices without tax, the style would be:

<div class="productPrices">
<div class="priceswithoutTax bold">£100.00</div>
<div class="priceswithTax">£120.00</div>
</div>

I can then style them accordingly. What the best way to do this please?

It would be nice as a new feature to made this a toggle for incl.tax or excl.tax possible.
Or maybe for B2B usergroup set excl.tax and for regular customers incl.tax (registered).

This looks a common use!
