Sims 2 Enabled Hidden Text Message Interaction?

The BHAVs for text messaging are within the default cellphone and I was wondering if someone could enable them to be used on demand.

It would be nice if the interaction could work like the 'Call... /Sim' interaction where you click on the sim and you are asked who you would like to text. Alternatively if that is not possible simply seeing the sim tap on the phone after being commanded to text is fun anyway.

I have seen poseboxes but there is nothing like an interaction.

I have tried and tried to do this but I think it's okay and it's time to ask for help. I hope someone is able to do this, hopefully it is pretty simple and I should let you know that making this would truly be fulfilling my greatest sim wish.

I have all EPs and all SPs playing on Mansions and Gardens.

Thank you.
