Hi there,

You will need to do quite a modifications in order for you to achieve this currently as you cannot simply add them and want them to be stored on your blogs params.

Having said that, if you require us to perform the customisation for you, you can always request for a quote from us at https://crm.stackideas.com and select "Customisations" . Our sales person would gladly send you a quote for the customisation that you have requested.

By the way, i do have work around for you, that is to use 'Fields' as you can see here for an example https://take.ms/d7UYW. Enabled this settings https://take.ms/W6K9Y and add them accordingly here https://take.ms/Hm2Vk

Please give it a try and see how it goes.
